face in their World Cup opener against Italy in Manaus on June 14.

McManaman continued: 'The fact Bale scored two goals in two finals and won two trophies, how could it have gone any better?'

'Apart
from getting greedy and wanting to win the league and score a goal in
every game like Cristiano (Ronaldo) does, I really don't think it does.

'I mean he scored 22 goals – 22 goals in your first season, that in itself is phenomenal.

'I
think moving to a new country, trying to learn a new language, and
trying to adapt to a new lifestyle – for a relatively quiet, shy lad – I
think he’s had an amazing, amazing season.

'And
I don’t think we’ve seen the best of him, that’s the thing. I think
we’ll see an even better Gareth Bale once he’s fit, he’s rested and he’s
had a full pre-season.'

The Conditions Zone - created by Lucozade, the official sports drink of the England team - recreates the conditions of Manaus by pumping in moisture and raising the temperature in its indoor arena at Canary Wharf. Teams can sign up to play for free and each player will be given an analysis by sport scientists and their personal information monitored by STATSports Technologies.
